The label paper and the connecting wire 903 are subjected to ultrasonic welding in combination with a welding head, and in this embodiment, the label paper and the connecting wire 903 each contain a component capable of ultrasonic welding, such as nylon, or other components. The die-cut label paper is output to the outside of the apparatus through a label paper output port 405, and in this embodiment, the die-cut label paper is rolled after being output. The connection line 903 with the label 902 welded thereto enters the second welding mechanism 5 from the connection line discharge port 405 via the guide member 7. The first holding device 602 pulls out the connecting wire 903 with the tag 902 welded thereto by a set length. The tag is located at the proximal end portion of the connection wire 903, that is, at the clamping position of the first clamping device 602, and the first clamping device 602 pulls out the connection wire 903 beyond the position of the first ultrasonic welding device 501 by a set length. When the first clamping device 602 pulls the connecting wire 903 to the set position, the second ultrasonic welding device 502 and the wire pulling device 504 move downwards, at this time, the connecting wire 903 is located between the wire pulling rod 517 and the wire fixing rod 516, and by the arrangement of the positional relationship between the second ultrasonic welding device 502 and the wire fixing rod 516, the welding head in the second ultrasonic welding device 502 is located right above the connecting wire at this time, the connecting wire 903 and the packaging film 901 can be subjected to ultrasonic welding. After fixing the connecting wire 903 to the packaging film 901 at the position of the second ultrasonic welding device 502, the connecting wire is pulled to be W-shaped by the connecting wire 903 by the wire pulling rod 517 in the wire pulling device 504, and simultaneously the first clamping device 602 moves inwards, until the label 902 is pulled to a set position close to the edge of the packaging film 901, the label is ultrasonically welded and fixed to the packaging film by the first ultrasonic welding device 501, the connecting wire 903 is ultrasonically welded and fixed to the packaging film 901 by the third ultrasonic welding device 503, the connecting wire is sheared by the wire shearing device 8, the wire shearing device is a scissor controlled by a cylinder, one welding process is completed, the packaging film 901 is wound by a set distance through the winding device, and the next welding process is performed, so that the packaging film 901 with the label 902 is formed. When the packaging film 901 is wound, as the label 902 is positioned at the position near the edge of one side of the packaging film 901, the other side of the packaging film 901 needs to be placed with packing paper, so that the packaging film 901 is not easy to slip due to inconsistent winding thickness of two sides during winding, and the subsequent packaging production is inconvenient.
The packaging film with a label produced by the packaging film production apparatus with a label according to the present embodiment has a connecting line 903 and a label 902 fixed in the width direction of the packaging film 901, the label 902 being located at a position close to the side edge of the packaging film 901, and a welding point 904 formed by an ultrasonic welding device at the intermediate position of the packaging film 901 and at the edge position of the other side edge, respectively. And the connection line between the two welding points 904 is in a loose state so that the whole connection line is W-shaped.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
